Commands that take a hostname [ disks ] parameter pair operate on all disks in the disklist(5) for that hostname if no disks are specified. Where hostname is also marked as being optional, the command operates on all hosts and disks in the disklist(5) when no hostname is given. Both hostname and disks are match expressions; see amanda-match(7) for a description.

The tapes listed will not be reused when their turn comes up again in the tape cycle. Note that if this causes the number of reusable tapes to drop below the amanda.conftapecycle value, Amanda will request new tapes until the count is satisfied again.

Tape marked no-reuse are available for recovery, marking them no-reuse is a security to be sure amanda will not overwrite them.

An uppercase letter reverses the sort order for that key. The default sort order is hkdlspbfw.

holding deletehostname [ disk [ datestamp [ .. ] ] ]

Delete holding files matching the given specification. At least a hostname must be provided.

holding list [-l] [-d] [ hostname [ disk [ datestamp [ .. ] ] ] ]

List holding files matching the given dump specification, or all holding files if no specification is provided. See amanda-match(7) for more information on dump specifications. With '-l', additional information (size, level, and whether the dump is outdated) is provided. With '-d', only outdated dumps are shown.

An outdated holding file is one which is not required for a restore of the most recent dump. Note that outdated dumps may still be required for restores at earlier dates. For example, assume that a DLE had a level 0 on Monday, level 1's Tuesday through Thursday, and a level 2 on Friday. Then the files required for a restore of Fridays (the most recent) dump are those from Monday (level 0), Thursday (level 1), and Friday (level 2). Tuesday and Wednesday's files are outdated.

Request three specific file systems on machine-a get a full level 0 backup during the next Amanda run.

$ amadmin daily force machine-a / /var /usr
amadmin: machine-a:/ is set to a forced level 0 tonight.
amadmin: machine-a:/var is set to a forced level 0 tonight.
amadmin: machine-a:/usr is set to a forced level 0 tonight.

Request all file systems on machine-b get a full level 0 backup during the next Amanda run.

$ amadmin daily force machine-b
amadmin: machine-b:/ is set to a forced level 0 tonight.
amadmin: machine-b:/var is set to a forced level 0 tonight.
amadmin: machine-b:/usr is set to a forced level 0 tonight.
amadmin: machine-b:/home is set to a forced level 0 tonight.

Undo the previous force request for /home on machine-b. The other file systems will still get a full level 0 backup.

Locate backup images of /var from machine-c. The tape or file column displays either a tape label or a filename depending on whether the image is on tape or is still in the holding disk. If the image is on tape, the file column tells you which file on the tape has the image (file number zero is a tape label). This column shows zero and is not meaningful if the image is still in the holding disk. The status column tells you whether the backup was successful or had some type of error.

$ amadmin daily tape
The next Amanda run should go onto tape 123456 or a new tape.

Show how well full backups are balanced across the dump cycle. The due-date column is the day the backups are due for a full backup. #fs shows the number of filesystems doing full backups that night, and orig KB and out KB show the estimated total size of the backups before and after any compression, respectively.

The balance column shows how far off that night's backups are from the average size (shown at the bottom of the balance column). Amanda tries to keep the backups within +/- 5%, but since the amount of data on each filesystem is always changing, and Amanda will never delay backups just to rebalance the schedule, it is common for the schedule to fluctuate by larger percentages. In particular, in the case of a tape or backup failure, a bump will occur the following night, which will not be smoothed out until the next pass through the schedule.

The last line also shows an estimate of how many Amanda runs will be made between full backups for a file system. In the example, a file system will probably have a full backup done every eight times Amanda is run (e.g. every eight days).
